Yes, you can.
If it is fabric paint by Tulip (aka Puffy Paint) then no. Wash away and stilll expect the glow!!
If you are painting over a semi gloss paint you wand to use trisodium phosphate or TSP on the wall before you start painting. This is a deglosser that will allow whatever paint you are using to adhere to the wall. tip: After using TSP on the wall, give it a soap and water wash to prevent the phosphate in TSP to cause mildew/mold damage.
Wash it
you can wash it out.
You can wash it right away after the paint is dry, but it is recommended you allow the paint to cure. Depending on the type of paint used, two to three weeks is not unusual.
No, it is not safe to wash paint down the sink as it can harm the environment and clog pipes. It is recommended to dispose of paint properly at a hazardous waste facility.
To achieve a smooth and even finish when applying white wash wall paint, it is best to start by preparing the surface by cleaning and priming it. Use a high-quality paint roller or brush to apply the paint in thin, even coats, working in small sections at a time. Make sure to blend the edges of each section to avoid visible lines or streaks. Allow each coat to dry completely before applying the next one, and consider using a paint additive to improve flow and reduce brush marks.
No. Usually when you paint your wash your walls down first and rinse. Once the paint is applied it becomes a sealant. If it's water-based paint it's possible any pet odor (from a dog lifting their leg to a cat spraying on the wall) could be trapped in the plaster. After washing down the wall well (or that particular spot) use vinegar and warm water and soak lightly the part of the wall that has the stain and be sure it's good and dry before painting.
As long as it is architectural or house paint, you can use it in a bathroom. However, an exterior grade paint will not wash or scrub as well as a paint formulated for interior use so a 100% acrylic interior paint in an eggshell or glossier sheen would be recommended.

If it's a water based paint it will wash off. If it's oil based it will come off only with thinners.
